SAFETY ATTACHMENT FOR LINOTYPES AND INTERTYPES.

Application filed September To all whom it may concern:

Be it known that I, HERMAN T. SUND- s'rnoM, citizen of the United States," residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Safety Attachments for Linotypes and Intertypes, of Which the following is a specificat1on.

This invention relates to new anduseful" improvements 111 a safety attachment for' linotypes and intertypes.

The object of the invention is to provide an attachment of the character described which will operate automatically to stop the matrices before they reach the intermediate channel of the linotype, in case they have been improperly assembled in the assembling elevator.

In operating a linotype, the matrlces are first assembled in the assembling elevator by means of which they are elevated into alignment with the intermediate channel through which they are sent on their way to the mold disc. are capable of being assembled in two positions, that is, in upper or in lower position. If the matrices are smaller than fourteen point, they may be assembled in lower or upper position so as to align perfectly with the mold disc when carried into position for casting. If over fourteen points they must be assembled in lower position, or they will not align'with said disc, and casting material will not be projected directly against said matrices, and an imperfect casting will result; and furthermore the molten material will escape, causing what is known as front overflow or front squirt. I

It is the object of this invention to provide an attachment of the character described which will automatically stop the matrices before they reach the intermediate channel, in case they have been assembled in the wrong position in the assembling elevator, and when the matrices have been so stopped, they can be then adjusted to the lower position before they are sent on through the intermediate channel to the molding disc of the linotype.

lVith the above and other objects in view, the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and Some of these matrices 5, 1922. Serial No. 586,314.

Flgure 1 shows a side elevation of the vise cap, of a hnotype, showmg an assembhng elevator and lntermediate channel assoclated therewlth, and

F gure 2 1s an enlarged fragmentary View, of the safety'attachment.

Referrmgnow more drawings wherem like numerals of reference designate slmilar parts in each of the figaccompanying drawings,

particularly to the ures, the numeral 1 indicates the first eleva-.

tor filling piece which is hingedto the top of the vise cap 2, by means of the hinge 3.

The matrices 4 are composed in an assembler or assembling elevator 5, and from thls elevator they travel along the intermed ate channel 6, on their way to the mold dlsc. In case matrices larger than fourteen points are assembled'in the upper position, in the assembling elevator, they will not align with the mold disc, provided for them and consequently, fore they reach said disc, to'lower position, so: as to come 1nt0 perfect alignment therewith. To permit said adjustment, said matr1ces must be stopped before they reach the mtermediate channel 6, and the attachment for stopping them for this adjustment w1ll now be described: a

A bar 7 is provided, one end of which is pivoted at the point 8 and the other end of wh ch has a limited vertical movement. Th1s last mentioned end is aligned over the line of matrices in the assembling elevator. The pivoted end of the bar has a depending integral arm 9 provided to interlock with one arm of the bell crank 10 which is pivoted should be adjusted beto the frame of the-channel 6. An actuating rod 11 is mounted upon the vise cap 2 and 1s slldable lengthwise in the bearing 12. The filling piece 1 has a laterally extending pin 13 projecting therefrom near its hinged end and the adjacent end of the rod 11 is bent upwardly at right angles forming the stud 14 against which the pinjl3 rests when the filling piece 1 is in active position. The

opposite end of the rod 11 carries'the bearing plate 15 which operates against the free end of the other arm of the bell crank 10.

When said filling piece 1 is in active position on the vise cap, as shown in Figure 1,]

the pin 13 operates against the stud 14 to actuate the rod 11 and force the plate 15 ing against the adjacent arm of the bell crank 10 and this operates to carry the other end of said bell crank into locking engagement with the arm 9. The bar 7 is thereby held locked against movement and should some of the matrices be improperly assembled in elevated position, as indicated in Figure 1, when the assembling elevator is elevated they will contact against said bar and be stopped before they are fully elevated into alignment with the intermediate channel 6, and consequently will not be able to pass along said channel to the mold disc, until they have been lowered into lower position. The stop of the matrices will attract the operators attention so that he will not overlook adjusting the same to proper position before they have entered the intermediate channel.

In case matriees of fourteen point or less are being assembled the filling piece 1 is thrown into inactive position, as shown in full lines in Figure 2, carrying the pin 13 out of contact with the stud 14 and releasthe bell crank 10 by the pull of a coil spring 16, one end of which is attached to said bell crank and the other end of which is attached to the frame of the intermediate channel. The pull of this spring operates to release the bell crank from locking engagement with the arinE), thereby unlocking the bar 7 and permitting the elevation thereof so that it will not interfere with the passage of said matrices, it being immaterial whether or not said last mentioned matricesare assembled in upper er lower position, as in either case they will align with the mold disc provided for them.

As is well understood in the art, the assembling elevator 5, when elevated into registration with the intermediate channel 6, trips a transfer carriage which shifts the composed line out of the elevator and through the intermediate channel into a so-called first elevator whereby the line is presented to the mold for the slug casting operation, the vertical position or level of the first elevator with refereiiee to the mold being determined by the filling piece 1 before mentioned. It is evident, therefore, that when the assembling elevator is arrested in its upward movement by the looking bar 7, it fails to trip the transfer carriage and hence allows the composed line to remain in the elevator. As a matter of fact, liOWGXKW, the same effect would follow even if the transfer carriage were tripped, due to the lack of registration of the assembling elevator and the intermediate channel. The transfer carriage and the first elevator, together with all other parts of the machine not herein shown, are so well known that it has not been deemed necessary to illustrate them herein. For the same reason, it has been thought unnecessary to enlarge upon the description of the known parts herein illustrated.
